DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figure 1-Figure 5 , an outdoor highly waterproof and safe power distribution monitoring terminal, comprising a chassis 1, and also comprising an air circulation part, a liquid circulation part and a heat dissipation part;

[0046] The air circulation unit is used for the circulation of air inside the chassis 1, and includes an air circulation box 7 fixedly mounted on the back of the chassis 1, on which two air collecting boxes 6 are fixedly mounted; a cover body 5 is fixedly mounted on the back of the chassis 1, and is used to protect numerous components mounted on the back of the chassis 1, and plays a certain role in preventing dust and water, which can effectively ensure the stability of the operation of the components and can also extend the service life of the components.

[0047] The function of the gas collecting box 6 is to collect the gas sucked out from the chassis 1 and then collectively suck it into the gas circulation box 7, ensuring that the air inlet is located below the gas circulation box 7 to make the gas circulation smoother;

[0048] The two air collecting boxes 6 are connected to the air circulation box 7 through a one-way pipe 14. A plurality of one-way pipes 25 are fixedly connected inside the air circulation box 7. An air outlet box 2 and an air inlet box 11 are fixedly installed inside the chassis 1. The air outlet box 2 and the air inlet box 11 are connected to the corresponding air collecting boxes 6 through a plurality of air guide pipes 4. A plurality of air outlet heads 3 are fixedly connected on the air outlet box 2, and a plurality of air inlet heads are fixedly connected on the air inlet box 11.

[0049] The air outlet head 3 and the air inlet head are evenly distributed on the corresponding air outlet box 2 and the air inlet box 11. The through-lay design can simultaneously extract air from different positions inside the chassis 1, so that the electronic components inside the chassis 1 can dissipate heat evenly. At the same time, multiple air inlets and outlets are used to speed up the air inlet and outlet speeds and improve the heat dissipation efficiency.

[0050] Two piston plates 16 are slidably installed in the air circulation box 7, a motor 13 is fixedly installed on the back of the box 1, and a driving mechanism is installed between the motor 13 and the two piston plates 16; the driving mechanism adopts a mechanical structure to cooperate with each other to produce a linkage effect, and has better stability. At the same time, one motor 13 is used as the only driving source, which reduces the number of motors 13, has low support costs, low energy consumption during operation, and has certain environmental protection.

[0051] The driving mechanism includes a screw rod 17 fixedly mounted on two piston plates 16, a nut 18 is threadedly mounted on each of the screw rods 17, a gear 19 is fixedly mounted on each of the nuts 18, and the two gears 19 are rotationally connected to the air circulation box 7;

[0052] This part uses the cooperation between the screw rod 17 and the nut 18 to drive the piston plate 16 to move up and down. Since the nut 18 moves relatively smoothly on the screw rod 17, the piston plate 16 moves up and down smoothly, making the air inlet and outlet more stable, which can effectively avoid the influence of the large change of the air inlet and outlet speed on the electronic components inside the chassis 1, and improve the stability of the operation of the electronic components;

[0053] An annular groove is provided on each of the two gears 19, and a plurality of support rods slidably connected to the corresponding annular grooves are fixedly mounted on the air circulation box 7; the annular grooves and the support rods are used to limit the position of the gear 19, ensuring that the gear 19 can only rotate on the air circulation box 7 but cannot move, thereby ensuring the stability of the coordinated operation of the nut 18 and the screw rod 17.

[0054] A gear 3 21 meshing with one of the gears 19 is fixedly mounted on the driving end of the motor 13, and a gear 20 meshing with the gear 3 21 is rotatably mounted on the top of the air circulation box 7, and the gear 20 meshes with another gear 19;

[0055] The function of this part is to make the two screw rods 17 rotate in opposite directions, so as to achieve the purpose of the two piston plates 16 moving in opposite directions and reciprocating, which can increase the air flow rate of a single inlet and outlet, thereby improving the heat dissipation efficiency.

[0056] Reference Figure 3 , Figure 6-7The liquid circulation part is used for circulating the heat in the air inside the heat exchange box 1, and the liquid circulation part includes a liquid circulation box 8 fixedly installed on the back of the air circulation box 7;

[0057] The liquid circulation box 8 is filled with coolant, and the coolant circulates in the liquid circulation box 8 to absorb the heat in the air carrying the heat, thereby achieving the purpose of heat transfer, thereby dissipating the heat of the air in the chassis 1. Compared with air cooling, cooling by coolant has higher heat dissipation efficiency and better heat dissipation effect.

[0058] A piston plate 26 is slidably installed in the liquid circulation box 8, and a transmission mechanism is installed between the motor 13 and the piston plate 26; the function of the transmission structure is to drive the piston plate 26 to move up and down through the motor 13. The driving source here is the same driving source as the driving source of the above-mentioned piston plate 16 (both are motors 13), which can reduce the number of motors 13 and achieve the purpose of reducing the energy consumption of heat dissipation operation.

[0059] The transmission mechanism includes a wedge block 27 fixedly mounted on the piston plate 26, a plurality of reset springs 28 fixedly mounted between the piston plate 26 and the liquid circulation box 8, and a pushing structure matched with the wedge block 27 is installed between the liquid circulation box 8 and the driving end of the motor 13; the reset spring 28 can automatically reset the piston plate 26, without the need for a power source to increase the power base, reduce the load on the driving end of the motor 13, protect the motor 13, and extend the service life of the motor 13.

[0060] The driving structure includes a linkage shaft 30 and a rotating shaft 34 rotatably mounted on the top of the liquid circulation box 8. Rollers are fixedly mounted on the upper part of the linkage shaft 30 and the driving end of the motor 13. A driving track 31 is sleeved between the two rollers. A first gear 32 is fixedly mounted on the lower part of the linkage shaft 30. A second gear 33 meshing with the first gear 32 is fixedly mounted on the rotating shaft 34. A toothed plate 29 meshing with the second gear 33 is slidably mounted on the top of the liquid circulation box 8. A pressure roller 35 cooperating with the wedge block 27 is rotatably mounted on the toothed plate 29.

[0061] By utilizing the cooperation between the pressure roller 35 and the wedge block 27, when the pressure roller 35 reciprocates once, the piston plate 26 can reciprocate twice. This can increase the operating frequency of the piston plate 26 in terms of movement, thereby increasing the number of circulations of the coolant in the liquid circulation box 8, thereby achieving the purpose of improving the heat dissipation efficiency.

[0062] Reference Figure 5-Figure 6 , a heat exchange mechanism is installed between the liquid circulation box 8 and the gas circulation box 7;

[0063] The function of the heat exchange structure is to exchange the heat in the air in the air circulation box 7 to the coolant in the liquid circulation box 8. The heat is transferred by heat exchange, which not only has the advantage of efficient heat dissipation, but also can keep the air in the chassis 1 to maintain the original air without replacement, prevent new air from entering, ensure that the chassis 1 is absolutely airtight, and prevent dust from entering the chassis 1 and affecting the electronic components.

[0064] The heat exchange mechanism includes a liquid guide cavity 23 provided inside the gas circulation box 7, a guide plate is fixedly installed inside the liquid guide cavity 23, a heat exchange plate 24 matched with the guide plate is fixedly installed inside the liquid guide cavity 23, and each one-way pipe 25 is connected to the liquid guide cavity 23; a plurality of hemispherical grooves are provided on the heat exchange plate 24, so that the inlet and outlet area of ​​the heat exchange plate 24 and the air in the gas circulation box 7 can be expanded, thereby accelerating the heat exchange, which has the advantage of improving the heat conduction efficiency;

[0065] A plurality of liquid guiding tubes 22 are fixedly connected to the bottom of the liquid guiding cavity 23, wherein the matching liquid guiding tubes 22 are commonly fixedly connected to a liquid outlet pipe 10, and the matching liquid guiding tubes 22 are commonly fixedly connected to a liquid inlet pipe 15, the liquid outlet pipe 10 and the liquid inlet pipe 15 are both connected to the liquid circulation box 8, a partition is fixedly installed in the middle of the liquid circulation box 8, and the liquid outlet pipe 10 and the liquid inlet pipe 15 are respectively located on both sides of the partition; the function of the partition is to isolate and partition the coolant, so as to ensure that the coolant carrying heat is separated from the coolant not carrying heat, thereby ensuring the heat absorption efficiency of the coolant, thereby improving the heat dissipation efficiency.

[0066] Reference Figure 3 , Figure 8 , Fig.11 The heat dissipation part is used to dissipate the heat after the heat exchange. The heat dissipation part includes a protective cover 9 fixedly installed on the back of the liquid circulation box 8. The upper part of the protective cover 9 is fixedly connected to a plurality of air cylinders 36. A rotating rod 41 is rotatably installed in each air cylinder 36. A heat dissipation impeller 48 is fixedly installed on each rotating rod 41. A plurality of heat dissipation fins 12 are fixedly installed in the liquid circulation box 8.

[0067] A plurality of circular holes are provided on the heat dissipation fins 12, and the purpose of such arrangement is to increase the contact area between the heat dissipation fins 12 and the outside air, accelerate the heat dissipation on the heat dissipation fins 12, and improve the heat dissipation efficiency.

[0068] Each heat dissipation fin 12 extends out of the liquid circulation box 8 and extends into the protective cover 9, and is located below the wind tube 36. A linkage mechanism is installed between the multiple rotating rods 41; the function of the linkage mechanism is to make the multiple heat dissipation impellers 48 rotate in the same direction at the same time, so that the multiple heat dissipation impellers 48 can operate at the same time, speed up the air circulation speed in the protective cover 9, and improve the heat dissipation efficiency.

[0069] The linkage mechanism includes a transmission disc 49 fixedly mounted on the rotating rod 41, a linkage track 42 is sleeved between the plurality of transmission discs 49, and a fitting structure matching the plurality of transmission discs 49 is mounted on the protective cover 9;

[0070] The function of the fitting structure is to ensure that each transmission disc 49 is in contact with the linkage track 42, so that the linkage track 42 can drive all transmission discs 49 to rotate simultaneously, and so that each heat dissipation impeller 48 can operate.

[0071] The fitting structure includes a plurality of elastic columns 50 fixedly installed in the protective cover 9, and a fitting bracket 37 is fixedly installed on the plurality of elastic columns 50. A first pressure plate 51 cooperating with the corresponding transmission plate 49 is rotatably installed on the fitting bracket 37, and each pressure plate 51 is against the linked crawler 42.

[0072] The elastic column 50 can apply a mortgage force to the fitting bracket 37, so that the pressure plate 51 and the linked crawler belt 42 are pressed against each other, and the linked crawler belt 42 is pressed against the transmission plate 49, so as to increase the friction between the linked crawler belt 42 and the transmission plate 49.

[0073] Reference Figure 9-10 , a driving mechanism is installed between the motor 13 and one of the rotating rods 41;

[0074] The function of the driving mechanism is to drive the heat dissipation impeller 48 to rotate through the motor 13, which is the same driving source as the driving source of the piston plate 16, to ensure that when the piston plate 16 is operating, the heat dissipation impeller 48 also operates at the same time, to achieve isochronous heat dissipation, and has a certain degree of efficient heat dissipation.

[0075] The driving mechanism includes a one-way bearing 43 fixedly mounted on the rotating shaft 34, a belt roller 39 fixedly mounted on the one-way bearing 43, a linkage roller 1 fixedly mounted on one of the rotating rods 41, a belt 40 is sleeved between the linkage roller 1 and the belt roller 39, and a reversing structure is installed between the rotating shaft 34 and the other rotating rod 41;

[0076] The function of the reversing structure is to keep the heat dissipation impeller 48 rotating in one direction regardless of whether the motor 13 driving end is rotating forward or reversely, thereby preventing the heat dissipation impeller 48 from reversing and blowing air upward, and ensuring that the heat dissipation impeller 48 always blows air downward to dissipate heat to the heat dissipation fins 12.

[0077] The reversing structure includes a gear disc 1 38 fixedly mounted on the rotating shaft 34, a pillar rotatably mounted on the liquid circulation box 8, a one-way bearing 2 47 fixedly mounted on the pillar, a gear disc 2 44 meshing with the gear disc 1 38 fixedly mounted on the one-way bearing 2 47, and a transmission structure installed between the pillar and another rotating rod 41; the function of the transmission structure is to drive the other rotating rod 41 to rotate, and it operates separately from one of the above-mentioned rotating rods 41.

[0078] The transmission structure includes a belt roller 2 45 fixedly mounted on the pillar, and a linkage roller 2 is fixedly mounted on another rotating rod 41, and a belt 2 46 is sleeved between the linkage roller 2 and the belt roller 2 45;

[0079] The specific operation steps of this power distribution monitoring terminal are:

[0080] Air circulation in the chassis 1: start the motor 13, the driving end of the motor 13 rotates to drive the gear three 21 to rotate, the gear three 21 rotates to drive the gear one 19 and the gear two 20 meshing therewith to rotate, and the gear two 20 drives the gear one 19 meshing with the gear two 20 to rotate, and the two gears one 19 rotate in opposite directions, so the two nuts 18 fixedly mounted on the corresponding gear one 19 rotate in opposite directions, so that the two lead screws 17 move in opposite directions, thereby driving the corresponding piston plate one 16 to move in the air circulation box 7, and the moving direction of the piston plate one 16 is changed by changing the direction of rotation of the driving end of the motor 13 to achieve the purpose of reciprocating movement, such as Figure 5 As shown, when the left screw rod 17 moves downward, the right screw rod 17 moves upward;

[0081] When the piston plate 16 moves, the space inside the air circulation box 7 is compressed, so that the air in the chassis 1 is sucked into the air circulation box 7 through the air inlet head and the air inlet box 11. The air in the air circulation box 7 enters the liquid guide cavity 23 through the one-way tube 25. However, due to the blocking effect of the heat exchange plate 24, the air will enter the other side of the air circulation box 7 along the heat exchange plate 24, and the piston plate 16 on this side will press the air back into the chassis 1 through the air outlet box 2 and the air outlet head 3 to realize air circulation (during this part of the air circulation, the driving end of the motor 13 rotates three times, and each three times is one reciprocating motion).

[0082] Liquid circulation: When the temperature in the chassis 1 reaches a certain level, the temperature sensing controller controls the driving end of the motor 13 to rotate to one reciprocating cycle every five turns. The driving end of the motor 13 rotates, and the linkage shaft 30 is driven to rotate through the driving track 31 and the roller, thereby driving the first gear 32 to rotate. The rotation of the first gear 32 drives the second gear 33 meshing therewith to rotate, thereby driving the toothed plate 29 to move. When the motor 13 rotates three turns, the pressure roller 35 on the toothed plate 29 is located on the right side of the wedge block 27 (such as Figure 6 As shown), at this time, the pressing roller 35 will not move the wedge block 27, so the piston plate 26 will not move at this time;

[0083] When the driving end of the motor 13 rotates five times, the tooth plate 29 will continue to move to the left (direction reference Figure 6), at this time, the pressing roller 35 presses the wedge block 27, so that the wedge block 27 drives the piston plate 26 to move downward. When the pressing roller 35 moves beyond the highest point of the wedge block 27, the pressing roller 35 continues to move to the left. At this time, the piston plate 26 moves upward under the action of the return spring 28. The reciprocating movement of the piston plate 26 will cause the coolant in the liquid circulation box 8 to circulate through the liquid outlet pipe 10, the liquid inlet pipe 15, the liquid guide pipe 22 and the liquid guide cavity 23.

[0084] Heat exchange: When the coolant passes through the liquid guiding cavity 23, the coolant will contact the heat exchange plate 24, so that the heat on the heat exchange plate 24 is transferred to the coolant to achieve heat exchange.

[0085] Heat dissipation: When the liquid circulation is not started, the heat in the gas circulation box 7 is transferred to the heat dissipation fins 12 through the gas circulation box 7 and the liquid circulation box 8. When the liquid circulation is started, the heat is transferred to the heat dissipation fins 12 through the coolant;

[0086] When the driving end of the motor 13 rotates forward, the second gear 33 rotates to drive the rotating shaft 34 to rotate, and the rotating shaft 34 drives the one-way bearing 1 43 to rotate, thereby cooperating with the use of the belt roller 1 39, the belt 1 40, the transmission plate 49 and the linked crawler 42 to drive multiple heat dissipation impellers 48 to rotate forward and blow air at the same time. At this time, the rotation of the rotating shaft 34 will also drive the gear plate 1 38 to rotate, and the rotation of the gear plate 1 38 drives the gear plate 2 44 meshing therewith to reverse, and under the action of the one-way bearing 2 47, the pillar will not be driven to rotate, so the belt roller 2 45 will not be driven to rotate, and the heat dissipation impeller 48 will drive the pillar forward in turn through the belt 2 46. The special rotation mode of the one-way bearing 2 47 will not cause the pillar and the one-way bearing 2 47 to get stuck, so the pillar can rotate forward normally;

[0087] When the driving end of the motor 13 reverses, the rotating shaft 34 will not drive the one-way bearing 1 43 to rotate, so the belt 1 40 will not rotate, and the gear plate 1 38 will drive the gear plate 2 44 to rotate forward, and the forward rotation of the gear plate 2 44 will drive the pillar to rotate forward, and cooperate with the belt 2 46 and the belt roller 2 45 to drive the heat dissipation impeller 48 to rotate forward for heat dissipation. At this time, the forward rotation of the heat dissipation impeller 48 will drive the one-way bearing 1 43 to rotate forward through the belt 1 40 and the belt roller 1 39. Similar to the above, the one-way bearing 1 43 will not affect the rotation of the rotating shaft 34.

[0088] The heat dissipation impeller 48 always keeps blowing air in a positive direction downward, blowing the heat carried by the heat dissipation fins 12 into the external air for heat dissipation.

[0089] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
